EHV, HV. MV Power System Studies

• EHV (Extra High Voltage) systems refer to electrical power transmission systems that operate at voltages higher than 345 kV, typically used for long-distance transmission of electrical power.
• HV (High Voltage) systems operate at voltages typically between 69 kV and 345 kV. These systems are used for efficient power transmission over medium to long distances.
• MV (Medium Voltage) systems are typically in the range of 1 kV to 69 kV and are used in industrial, commercial, and residential distribution networks.

Power system studies are essential for ensuring the efficient, safe, and reliable operation of electrical power systems. These studies help engineers to analyze and design power networks, identify potential issues such as voltage instability, equipment overloading, and ensure that protection systems are properly designed to prevent system failures.

Several studies are carried out to ensure the stability and reliability of power systems:

• Load Flow Analysis: Determines the distribution of voltage, current, and power throughout the network under normal and peak conditions.
• Short Circuit Analysis: Identifies fault levels and evaluates protection coordination to ensure the network can handle short circuit events.
• Dynamic Stability Studies: Analyzes the system’s ability to withstand disturbances like faults, line outages, or generator failures.
• Transient Stability Analysis: Assesses the system’s ability to return to stable operation after a disturbance.
• Protection Coordination: Ensures that protective devices such as circuit breakers and relays operate correctly during faults to minimize damage.
• Harmonics Analysis: Evaluates the impact of non-linear loads on the system and identifies any harmful harmonic distortion.

Power system studies identify potential issues in the network such as overloading, inadequate protection schemes, and voltage instability. By conducting these studies, engineers can design systems that are more robust, select appropriate protection devices, and implement corrective measures before issues occur. This minimizes the risk of power
outages, equipment damage, and system failures.

Our power system study services are beneficial to:

• Utility Companies responsible for power generation, transmission, and distribution.
• Industrial Facilities with large-scale electrical systems requiring high reliability.
• Engineering Consultants needing comprehensive analysis for project design and
  implementation.
• Government and Regulatory Bodies for compliance with safety and operational
  standards.

Our team uses advanced simulation software tools such as PSSE, ETAP, DIgSILENT PowerFactory, and PSCAD to perform detailed modeling and analysis of the power system. We gather data on system components, load profiles, fault conditions, and network configurations to simulate real-world operating conditions and identify potential weaknesses or inefficiencies.

The duration of a power system study depends on the complexity and scope of the project. Small to medium-sized systems can typically be studied in a few weeks, while more complex EHV systems might require several months for in-depth analysis and simulation.
